Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Background. The development of alternative processes to eliminate pathogenic agents in water is a matter of growing interest. Current drinking water disinfection procedures, such as chlorination and ozonation, can generate disinfection by-products with car ...
Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is con ...
The incapability of conventional biological wastewater treatment to remove effectively biorecalcitrant and/or toxic pollutants, as well as the shortage of world water resources have promoted the research of more efficient and ecologically y friendly water ...
UV disinfection of viruses frequently leads to tailing after an initial exponential decay. Aggregation, light shielding, recombination or resistant virus sub-populations were proposed as explanations; however, none of these options has conclusively been de ...
The inactivation of coliphage MS2 by iron- and copper-catalyzed Fenton systems was studied to assess the importance of this process for virus inactivation in natural systems and during water treatment by advanced oxidation processes. The influence of H2O2 ...
Despite the widespread use of UV254 irradiation and solar disinfection for water treatment, little is known about the photochemical pathways that lead to virus inactivation by these treatments. The goal of this study was to identify reactions that occur in ...
I discuss the general trends emerged at the 11th International Conference on Vacuum Ultraviolet Radiation Physics in Tokyo, and in particular the impact of the new generation of ultraviolet and x-ray synchrotron sources. ...
The formation of bromate levels exceeding the drinking water standard of 10 mu g L-1 may impose the reduction of ozone doses used in the treatment of drinking water. This paper illustrates the procedure of evaluating the use of reduced ozone doses while im ...
The increase of bacterial resistance against various disinfection processes is a worrying phenomenon. As a consequence, the search for alternative techniques for fighting micro-organisms has become one of the major issues of these last few years. In this d ...
